Museums that house Renaissance oil paintings typically store them in environments that are carefully kept

Museums that house Renaissance oil paintings typically store them in environments that are carefully kept within narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the kind of oil paint used in these paintings actually adjusts to climatic changes quite well. If, as some museum directors believe, paint is the most sensitive substance in these works, then by relaxing the standards for temperature and humidity control, museums can reduce energy costs without risking damage to these paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to withstand signifiant variations in humidity.In the argument above, the two portions in boldface play which of the following roles?(A) The fist is an objection that has been raised against the position taken by the argument; the second is theposition taken by the argument.(B) The fist is the position taken by the argument; the second is the position that the argument calls intoquestion.(C) The fist is a judgment that has been offered in support of the position that the argument calls intoquestion; the second is a circumstance on which that judgment is, in part, based.(D) The fist is a judgment that has been offered in support of the position that the argument calls intoquestion; the second is that position.(E) The fist is a claim that the argument calls into question; the second is the position taken by the argument.
